Texas Instruments develops HVM for poLight optical MEMS component

February 23, 2012 — poLight, maker of reflowable autofocus actuated lenses, collaborated with Texas Instruments (TI) to produce the optical micro electro mechanical system (MEMS) component of poLight’s TLens, aiming for faster focus time and lower power consumption.

Texas Instruments worked closely with poLight to develop a cost-effective and performance-oriented manufacturing process. TI shared its advanced MEMS development and processing expertise, along experience in very high volume manufacturing (HVM), said Faa-Ching Wang, manager of the Heater Chip Business Unit at Texas Instruments.

poLight has 3 actuated autofocus devices based on a patented technology using Optical MEMS and polymer to fit camera modules based on 1/5"-1/2.5" sensors, reaching 5-12MP resolutions. The tunable lens device, TLens, is an alternative to voice coil motor (VCM) technology. poLight reports that the MEMS-based image sensors are more than 20x faster while consuming 40x less power than VCMs.
